VNC Server for Linux: A Comprehensive Guide for Devs

Hey there, Dev! Are you tired of constantly having to physically access your Linux machine to perform tasks? What if we told you that you could remotely access it from another device using VNC? In this journal article, we’ll cover everything you need to know about VNC Server for Linux, including its installation, configuration, and usage.

What is VNC Server?

VNC (Virtual Network Computing) is a desktop sharing system that allows you to remotely control another computer’s desktop. VNC Server is the software that needs to be installed on the computer that you want to control remotely.

VNC Server for Linux allows you to remotely access and control your Linux machine from another device, such as a Windows PC, Mac, or even a mobile phone.

Installing VNC Server for Linux

The first step in using VNC Server for Linux is to install the software on your Linux machine. The installation process may vary depending on your Linux distribution, but we’ll cover the general steps below.

Step 1: Update your Packages

Before installing any new software, it’s important to ensure that your system is up to date. You can do this by running the following command:

Command	Description
sudo apt-get update	Updates the package list on Ubuntu/Debian-based systems
sudo dnf update	Updates the package list on Fedora-based systems
sudo pacman -Syu	Updates the package list on Arch-based systems

You may be prompted to enter your root password to continue. Once the update is complete, proceed to the next step.

Step 2: Install VNC Server

Next, you’ll need to install the VNC Server software. You can do this by running the following command:

Command	Description
sudo apt-get install vncserver	Installs VNC Server on Ubuntu/Debian-based systems
sudo dnf install tigervnc-server	Installs VNC Server on Fedora-based systems
sudo pacman -S tigervnc	Installs VNC Server on Arch-based systems

You may be prompted to enter your root password to continue. Once the installation is complete, proceed to the next step.

Step 3: Configure VNC Server

Now that VNC Server is installed, you’ll need to configure it to set up a VNC connection. You can do this by running the following command:

Command	Description
vncserver	Configures VNC Server and creates a VNC password

You may be prompted to enter a password for VNC Server. This password will be used to authenticate remote connections to your Linux machine. Once you’ve entered your password, VNC Server will be configured and ready to use.

Using VNC Viewer to Connect to VNC Server

Now that VNC Server is installed and configured on your Linux machine, you can use VNC Viewer to connect to it from another device.

Step 1: Install VNC Viewer

You’ll need to install VNC Viewer on the device that you want to use to connect to your Linux machine. You can download VNC Viewer for free from the RealVNC website.

Step 2: Connect to VNC Server

Once you’ve installed VNC Viewer, you can use it to connect to your Linux machine. The exact steps may vary depending on your device and operating system, but the general process is as follows:

1. Open VNC Viewer
2. Enter the IP address or hostname of your Linux machine
3. Enter the VNC Server password that you created in the previous step
4. Click “Connect”

If everything is configured correctly, you should now be able to remotely access and control your Linux machine from your device using VNC Viewer.
